The Engine warning light "visit workshop" came on. The mechanic did some diagnostics, reset the computer and gave it a test drive before delivering back to me saying there is no problem.. I sat in the car with the engine ilding, 5 minutes later the light was back on. Has anybody else had a similar problem? This is a 2009 Cayman S 3.4?
Supplementary info: The engine temperature has remained at 80 and the oil level is full. Only used Shell V-Power fuel and performance seems unaffected.
You need to take it back, and have him read the code, not just clear it.
